Deer and elk, minimum 15. 5 in the gun 10 in a belt/pack pouch. That would be day trip count... if I'm in the field overnight or are going to be doing a lot of hiking, I'll throw another 20 in the pack, so total 35...
Only need 1 for the elk/deer

, but might need more for survival, or protection from other things that go boo in the night.
rodents and the like... as many as I can pack

Hate to have to go home early if I run out of ammo.
